BEARING. FOR SINGLE-DISK FURROW-OPENERS.

Application filed. September 7, 1915. Serial No. 49,320.

To all whom it may concern.

Be it known that I, Gnome PERKS, a citizen of the United States, residing at Springfield, inthe county of Clark and State of Ohio, have invented certain new and useful Improvements in Bearings for Single- Disk F arrow-Openers, of which the following is a specification.

This invention relates toimprovements in bearings for single disk furrow openers for seeding machines.

The object of the invention is to provide a. bearing of the character referred to which will be simple in construction and in which provision may be easily and simply effected for taking up wear.

In the accompanying drawings: Figure 1 is a vertical sectional view of a portion of a disk furrow opener and its support showing my bearing improvements, the section being on the line 11 of those parts shown v1n Fig. 2. Fig. 2 is a section on the l1ne 22 of Fig. 1. Fig. 3 is a plan View .of the two part bushing.

In said drawings 1 represents the usual suppoitwhicli is attached to the rear end of the drag liar (not'shown) this support being provided with the usual oil reservoir 2 leading to the bearing. The disk 3 is of the usual concavo convex form and has secured on the concave side thereof and about the central opening thereof the usual cup-shaped hub portion 4 having the centrally arranged trunnion 5 which projects through the opening. Located in the support 1 are the mem- -..bers 6 and 7 of a two-part bushing, each member; having a projecting lug 8 on its outer periphery which projects into a recess 9 in the support to prevent the bushing members from turning. The cored out portion of the support which receives these bushings is enlarged at the outer end to form a shoulder 10 and each bushing member is provided with a peripheral flange 11 at its extreme outer end to engage the shoulder 10. The

trunnion 5 is j ournaled in the two-part bushing and has a plate 13 clamped to the outer end of the sameby the head of a bolt 12 extended through the trunnion; said plate embracing the ends of the bushing members so as to prevent lateral dis lacement of the iparts. The inner side of t e support 1 ex tends within the cup-shaped hub 4 and is shaped to form a recess to receive packing material 14 to exclude dust at that point,

1 por a trunnion and the outer end of the bore of the support recelves a cap 15 for the same purpose.

The bushing members are so disposed that the dividing line between the same is in a vertical plane and the meeting faces of the respective members of the bushing are provided withadjacent recesses 16, the upper pair of which will stand in line with the oil conduit 2 so as to permit the oil to find its way to the wearing surfaces between the bush ng members and the trunnion; the meet ng faces of said bushingbeing further provided with longitudinally extending channels 17 to facilitate the passage of the lubricant to the extreme ends of the bearing surfaces.

In the original assembly of the parts, the bushing members will be so proportioned that a space will be left between the meeting faces thereof in order to permit thesame to be adjusted toward each other to take up Patented June 6, 1o1

wear, an adjusting screw 19 threaded into tllge support 1 and bearing against the la 8 o ployed for this purpose.

By this construction it will be seen that an one of the bushing members being embe quickly and easily assembled and in which f provision is made for readily adjusting the same to take up wear.

Having thus described my invention, I

clalm 1. In a bearing for disk furrow openers, a

support, a disk having a central opening, a trunnion secured to said disk, a divided bushing arranged in said support in a mannor to prevent rotation thereof, said trunnionbeing journaled in said bushing members, said support and bushing members having a shoulder and flange respectively, and

asupport, a disk having a central openlng, a

cup-shaped hub portion secured to said disk about said opening onone side of said supproj ectingr centi' ally from said hub portion, a divided bushing arranged in said supportstogether with-means for pre venting rotation of same, said-"support and bushing members, having, ac shoulder and flange respectively, and 'a clamping pl tese;

prevent lateral displacecured to the inner end of said trunnion and embracing the inner ends of said hashing members on the opposite side of said support to prevent lateral dispiacement ol the 5 parts.
